Not All Gravitational Waves Start With a Bang
A post about the different types of gravitational waves and where they come from, on my new blog, Three Alpha:
You’ve probably heard of gravitational waves. They’ve been in the news a lot recently because of two experiments called LIGO and Virgo, which have detected gravitational waves coming from some of the most violent events in the Universe – black holes merging and an enormous explosion known as a kilonova. But did you know there are other kinds of gravitational waves which haven’t been detected yet and which don’t start out so spectacularly?
